Takeaway
Higher serum magnesium (Mg) concentrations were associated with reduced risk of intracranial aneurysm and aneurysmal subarachnoid hemorrhage.
Why this matters
Serum Mg is implicated in blood pressure (BP) regulation and vascular endothelium function, but it was previously unknown whether it affects the risk of intracranial aneurysm and subarachnoid hemorrhage.
Results of this study indicate a beneficial role of higher Mg for prevention of cerebrovascular and cardiovascular diseases and may have future treatment implications.
